Lung cancer has the highest morbidity and mortality rate among malignant tumors. Early diagnosis and effective treat-ment are the keys to improving the survival of lung cancer patients. A type of endogenous, highly conserved, non-coding small mole-cule RNA (i.e., miRNA) was found to play an important role in the occurrence and development of this disease. Research on this molec-ular marker miRNA for the diagnosis, treatment and prognosis of lung cancer has rapidly progressed. This paper reviews the research work on miRNA as a molecular marker in the early diagnosis, treatment efficacy, and prognosis of lung cancer and explores some ques-tions related to this disease.

Mild cognitive impairment (MCI) is considered as an intermediate clinical state between normal aging and Alzheimer’s disease (AD). The cognitive function and life ability of patients are normal, which have not met the criteria of AD. MCI is considered to be an earlier stage of AD. The clinical effects of AD in the middle or late stage are unsatisfactory. Therefore, studies on MCI have become the hot research areas both at home and abroad. The therapy of MCI is similar to AD. The treatment effect is uncertain. Hence, the understanding and treatment of MCI by TCM reflected TCM features. This article reviewed on TCM understanding of MCI, TCM syndrome differentiation criteria and TCM treatment methods of MCJ. Thus, it was aimed to further understand the dynamic of MCI in order to provide references for improving TCM clinical effects and reducing the incidence of AD.

OBJECTIVE:To establish a method for simultaneous determination of pulchinenoside B4,caffeic acid,baicalin, palmatine hydrochloride and berberine hydrochloride in Baipuhuang tablets. METHODS:HPLC method was adopted. The determi-nation of Agela Technologies Venusil XBP C18(L)with mobile phase consisted of acetonitrile-0.05 mol/L monopotassium phosphate (gradient elution)at the flow rate of 0.8 mL/min. The detection wavelengths were set at 203 nm(pulchinenoside B4)and 323 nm (caffeic acid,baicalin,palmatine hydrochloride,berberine hydrochloride). The column temperature was set at 30 ℃,and the sam-ple size was 10 μL. RESULTS:The linear ranges were 0.08141-8.141μg for pulchinenoside B4(r=0.9998),0.01871-1.871 μg for caffeic acid (r=0.9994),0.03733-3.733 μg for baicalin (r=0.9992),0.02885-2.885 μg for palmatine hydrochloride (r=0.9996) and 0.02758-2.758 μg for berberine hydrochloride (r=0.9997). The limits of quantitation were 0.009,0.006,0.008, 0.011,0.013 ng,respectively. The limits of detection were 0.030,0.020,0.025,0.034,0.036 ng,respectively. RSDs of preci-sion,stability and reproducibility tests were all lower than 2.0%. The average recoveries were 97.39%-102.34%(RSD=1.81%,n=6),96.77%-98.92%(RSD=0.85%,n=6),97.38%-103.72%(RSD=2.46%,n=6),96.73%-102.01%(RSD=2.22%,n=6)and 96.47%-101.07%(RSD=1.61%,n=6),respectively. CONCLUSIONS:The method is simple,accurate and reproducibility,and can be used for simultaneous determination of pulchinenoside B4,caffeic acid,baicalin,palmatine hydrochloride and berberine hy-drochloride in Baipuhuang tablet.

Objective The effect of oral L-Dopa on healing of the experimental mandibular defect of rabbits was studied.Method 52 rabbits were assigned randomly to experimental group and control group.After bone defect being made on mandible,rabbits had been given with L-Dopa in experimental group.Healing bone samples were adopted at 14,21,30,42,49 days after operation,observed x-ray and histological changes and calculated out the bone histomorphometric parameters.Results X-ray inspection indicated that bone defect of the experimental group had completed callus union from 30th day.But,a part of the defect of control group did not appear callus union radiologically.Histological examination had the same result.Bone histormorphometry examination exhibited that there was a significant difference between TBV of the experimental and the control group(P

Objective To research the mechanism of TX0201 abstracted from Heart-Regulating Formula in treatment of rats with Alzheimer's disease (AD). Methods The rat model of AD was induced by A?25-35 injected into the bilateral amygdale. To observe the spatial learning and memory ability, by means of RT-PCR and immunohistochemistry analysis, the expression of ?-amyloid precursor protein (APP), glial filament acid protein (GFAP) in the brain of the model animal were examined. Results In AD model group, the spatial learning and memory ability was damaged significantly, the expression of APP mRNA increased in its cortex and hippocampus. GFAP immunopositive signal, and IL-6 mRNA in cortex and hippocampus and the expression of IL-1? mRNA in hippocampus were upregulated. TX0201 improved the spatial learning and memory disturbance, decreased the expression of APP mRNA and IL-1? mRNA in hippocampus, downregulated GFAP and IL-6 mRNA in cortex and hippocampus. Conclusions The model showed the characteristic of AD such as memory hypofunction. TX0201 could partially ameliorate memory function, decrease the expression of APP mRNA in hippocampus, alleviate inflammation-immunity reaction, that is one of the effect mechanisms of TX0201.
